Thank you! I couldn’t believe it but with your mod the NVMe in a PCIe adapter DOES show in the boot menu of the BIOS. It even booted off a cloaned MBR drive, and did until I converted it to GPT. Any tips there?
EDIT: I made a 100MB patition at the begining of the drive and rebuilt the BCD with EasyBCD, now windows boots! I didn’t have to reinstall!!!
